When adding curves there are some common options like other Objects.
Note
Eventually all the primitive curves will be replaced to use the same curve system used for hair curves. Until this is done, their features will diverge.
They can be converted interchangeably to access the full range of edit and sculpting functionalities.
In Object/Edit Mode, the Add Curve menu, provides a few different curve primitives:
Bézier Curve
Adds an open 2D Bézier curve with two control points.
Bézier Circle
Adds a closed, circle-shaped 2D Bézier curve (made of four control points).
NURBS Curve
Adds an open 2D NURBS curve, with four control points, with Uniform knots.
NURBS Circle
Adds a closed, circle-shaped 2D NURBS curve (made of eight control points).
Path
Adds a NURBS open 3D curve made of five aligned control points, with Endpoint knots and the Curve Path setting enabled.
